The 9S can be used stand-alone or together with multiple subwoofer units. Using multiple units may be helpful if
the listening room is large or has difficult acoustic conditions. When using two or more subwoofers, the first one
(designated “Master”) controls the following subs (designated “Slave”) via a subwoofer cable.
To connect multiple subwoofers:
1. Connect the first subwoofer as described previously.
2. Set the Mode switch of first subwoofer to LFE.
3. From the Slave output of the first subwoofer connect a XLR cable to the LFE/Slave input of the following subwoofer. This
one now becomes the slave.
4. Set the Mode switch of the second subwoofer to Slave.
Further subwoofers can be connected in the same way. Set the Mode switch of all following subwoofers to Slave.
Notes
When using multiple subwoofers in a Master-Slave setup, it is recommended that the subwoofers are all the same
model.
If you wish to use multiple subwoofers with full individual control, set the Input switch for all to the LFE position.
From the source subwoofer output, use a Y-connector.
